Specification of Letters Patent.

Application filed January 16, 1914. Serial No. 812,605.

To all whom it may concern:

Be it known that I, FREDoLrEN J. OBERER, a citizen of the United States, and a resident of the city of Portland, county of Multnomah, State of Oregon, have invented a new and useful Improvement in Combined Door Hinges and Fastenings, of which the following is a specification.

My invention relates to the hinging and fastening of a door, or closure, which is so located as to be hard to operate; and my invention has for its general purpose the providing of hinging and fastening means conveniently and easilyoperated andso arranged as to be operable by one hand.

It is also the purpose of my invention to so construct my fastening means for the door that they will operate to lock the latter at its fourcorners, and by so doing hold it more securely than if fastened as usual.

An incidental object of my invention is to provide hinging and fastening means for a door which will give both strength and stability, and withstand the varying stresses due to changes of temperature.

My invention was especially suggested by the needs of a silo door, but may also be used to advantage in many other instances.

The construction, application and operation of my invention will be more readily understood by having reference in the first instance to the accompanying drawings, in which:

Figure 1 is a fragmental front elevation of a silo in which the doors are provided with hinging and fastening means invented by me; Fig. 2 is a horizontal section taken approximately on the line 2-2 of Fig. 1, through one of the silo doors; this figure showing the relative position of the operating parts when the door is closed; Fig. 3 is another view like Fig. 2, showing the position of the operating parts when the door has been released from its jamb; and the broken lines of this figure show how, after the door has been so released, it may be swung inward on its hinge brackets; and Fig. 4 is a detail of construction.

The door j ambs, a, of the silo are rigidlyheld spaced apart by spacing-bars, 6, set transversely at the top and bottom of the door openings, and constituting the top and bottom of the door frame. These bars, b,are shown only in Figs. 2 and 3. Angle-irons, c, are bolted to the jambs, a, andthe spacing-bars b, said angle-irons constituting the sills and top of the door-frame; and the door jambs, a, being formed by the staves, cl, of the body of the silo. Said staves are tongued and grooved together in the usual manner so as to give an air-tight fit when compressed together. Swivel lugs, e, are journaled between each pair of angle-irons, c, and have threaded into them the ends of adjustable tightening bands or hoops 7". On the angle-irons c are pivoted at c the hinge-brackets, g, supporting the top and the bottom of the door. Said hinge-brackets are each made with a gear segment 9, of which the pivotal point 0 is the center. Said hinge-brackets are each further made with a hinge pintle g and a perpendicularly projecting stop 9 (shown more clearly in Fig. 1) which limits the rotation of the hinge-brackets.

The doors 7;, are made in the usual manner and are provided on the outside with cross braces h on which are mounted ladder rungs 72. as shown in Fig. 1. The doors are adapted to swing inside of the silo and when closed will overlap the edges of the door jambs (as shown in Figs. 2 and 8) and also the spacing bars 7). Near the top and bottom portions of each door is fastened transversely a metal strap 2', one end of which is made with a hinge-knuckle z" for the pintle g of the hinge bracket 9. The other end of the strap, 2', is formed with a lock-lip 2' as shown in Figs. 2 and 3. The doors h are arranged one above the other.

The operating mechanism for the doors consists of a vertical shaft m journaled at its ends in the angle-irons 0, located at the bottom and the top of the door. Rigidly mounted on the end of the shaft m are pinions m which mesh with the'related gearsegments 9 of the hinge brackets g. A handle n is fastened on the shaft m so as to render the partial rotation of the latter convenient, by which'the door opening and fastening means are actuated. To each pinion m is connected one end of a bar 0, longitudinally movable in a bearing 79, fastened on the related angle-iron c. The bars 0 serve the purpose of latch-bolts.

In explaining the operation of my improvement, let it be assumed that the door is closed as shown in Fig. 2. The handle at is seized and given a quarter turn, thereby bringing it to its position in Fig. 3. Such action has withdrawn the latch-bolts, 0, from their engagement with the lock-lips 77 The rotation of the shaft m has also caused the pinions m to so move the gearsegments g as to position the hinge-brackets g as shown in Fig. 3; in so doing moving the door it inward from. its jamb; and the door may then be swung to the left as shown in dotted outline in Fin. 3) so as to clear the door opening. When later the door is again to be shut, it will first be moved back to its position shown in full lines in Fig. 3. The handle a will then be given a quarter turn to the left, thereby ro tating the shaft m and therewith. the pinions m, which will move the gear segment 9' outward; in so doing drawing the door against its jamb, and finally projecting the extremities of the latch bolts, 0, behind the lock-lips i The operated parts have now been restored to the position in which they are shown in F 2, and the door will be secured in place at each of its four corners.

The detail Fig. 4 shows that the pinions m are made with stub-axles m journaled in the angle plates 0 and held in place by means of keys m The pinions m have square eyes extending only part way through, in which square eyes are set the ends of the shaft m.

Fig. 4 also shows more clearly that the pinions m are made with flanges m for restraining the gear segments 9 against movement in a vertical plane. The lower of the hinge brackets g bears upon the door sill and the upper thereof against the top of the door casing. The construction shown effectively holds the hinge brackets against rotation in a vertical plane, either longitudinally or transversely.

It will be noticed from Fig. 2 that when the door is closed and latched, as described, the ends of the latch bars, 0, fastened to the pinions m, are so located as to hold said pinions against reverse rotation while the opposite ends of said latch bars are forced wedge-like behind the lock-lip 2' it being understood that the latch bars have some spring.

I claim:
